     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  log

------------------------------+-------------------------
 I'm build Boost 1.63.0 on Solaris 11.3 x86 using Developer Studio 12.5.

 I use the following command to do the build:

 ./b2 link=shared runtime-link=shared address-model=64 threading=multi
 variant=release cxxflags="-std=c++14" linkflags="-std=c++14"

 The above build fails in Boost.Log with the error message:

 "libs/log/src/named_scope.cpp", line 118: Error: Overloading ambiguity
 between
 "boost::optional<boost::log::v2_mt_posix::attributes::named_scope_list>::operator=<boost::log::v2_mt_posix::attributes::named_scope_list&>(boost::log::v2_mt_posix::attributes::named_scope_list&)"
 and
 "boost::optional<boost::log::v2_mt_posix::attributes::named_scope_list>::operator=<boost::log::v2_mt_posix::attributes::named_scope_list&>(boost::log::v2_mt_posix::attributes::named_scope_list&)".

 I have looked at the file where the error is occurring but due to my
 unfamiliarity with this area of Boost, I couldn't figure out what the
 problem is.
 However, it is possible that the problem could have something to do with
 Boost.Optional.

 Can you let me know what I can do in order for the Boost build to
 successfully generate the Boost.Log library files.
